[Chemical and DNA analyses for the products of a psychoactive plant, Voacanga africana].

Yakugaku Zasshi August 1, 2009 Ruri Kikura-Hanajiri, Takuro Maruyama, Akinori Miyashita et al. 15 citations

Voacanga africana (Apocynaceae) is a small tropical African tree. The root bark and seeds of this tree contain a number of alkaloids, including ibogaine (a hallucinogenic/aphrodisiac compound in bark), tabersonine (a major constituteent of seeds) and other voacanga alkaloids, traditionally used in Africa for religious purposes. Recently, some kinds of products containing this plant (root bark...

[Authentication and ultra performance liquid chromatography (UPLC)/MS analysis of magic mint, Salvia divinorum and its related plants].

Yakugaku Zasshi 2008 Takuro Maruyama, Hiroyuki Kamakura, Ruri Kikura-Hanajiri et al. 14 citations

Ultra performance liquid chromatography (UPLC)/mass spectrometry (MS) analysis was performed to investigate whether commercial Salvia cultivars available in the Japanese market contain salvinorin A (1), which is an hallucinogen present in magic mint (Salvia divinorum) prior to the regulation of S. divinorum by the Japanese Pharmaceutical Affairs Law. In addition, a previously reported method to...

Phylogenetic relationship of psychoactive fungi based on rRNA gene for a large subunit and their identification using the TaqMan assay (II).

Forensic Science International November 10, 2006 Takuro Maruyama, Nobuo Kawahara, Kazumasa Yokoyama et al.

"Magic mushroom (MM)" is the name most commonly given to psychoactive fungi containing the hallucinogenic components: psilocin (1) and psilocybin (2). We investigated the rRNA gene (internal transcribed spacer (ITS) and large subunit (LSU)) of two Panaeolus species and four Psilocybe species fungi (of these, two are non-psilocybin species). On the basis of sequence alignment, we improved the...

[DNA and chemical analyses of commercial fly agaric-related products].

Shokuhin eiseigaku zasshi. Journal of the Food Hygienic Society of Japan April 1, 2005 Takuro Maruyama, Nobuo Kawahara, Toshimitsu Fukiharu et al.

Since June 6, 2002, psilocin and psilocybin-containing fungi (commonly called "magic mushrooms") have been regulated by the Narcotics and Psychotropics Control Law in Japan. However, various fly agaric-related products are now entering the Japanese market via the internet. In this study, fly agaric-related products available in this way were investigated for raw materials by DNA analysis and...

Phylogenetic relationship of psychoactive fungi based on the rRNA gene for a large subunit and their identification using the TaqMan assay.

Chemical & pharmaceutical bulletin June 1, 2003 Takuro Maruyama, Kazumasa Yokoyama, Yukiko Makino et al.

"Magic mushrooms" (MMs) are psychoactive fungi containing the and Psychotropics Control Law in Japan. Because there are many kinds of MMs and they are often sold even as dry powders in local markets, it is very difficult to identify the original species of the MMs by morphological observation. Therefore, we investigated the rRNA gene for a large subunit (LSU) of several MMs to classify them by...

Discrimination of Psychoactive Fungi (Commonly Called "Magic Mushrooms") Based on the DNA Sequence of the Internal Transcribed Spacer Region.

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi) 2003 Takuro Maruyama, Osamu Shirota, Nobuo Kawahara et al. 14 citations

'Magic mushrooms' (MMs) are psychoactive fungi containing the hallucinogenic compounds, psilocin (1) and psilocybin (2). Since June 6, 2002, these fungi have been regulated by the Narcotics and Psychotropics Control Law in Japan. Because there are many kinds of MMs and they are sold even as dry powders in local markets, it is very difficult to identify the original species of the MMs by...
